Subregion

A subregion is a part of a larger geographical region or continent. Cardinal directions are commonly used to define subregions. There are many criteria for creating systems of subregions; this article is focusing on the United Nations geoscheme, which is a changing, constantly updated, UN tool based on specific political geography and demography considerations relevant in UN statistics.

United Nations subregions

The Statistics Division of the United Nations (UN) is in charge of the collection, processing, and dissemination of statistical information for the UN.^[1] In 1999, it developed a system of macro-geographical (continental) regions, subregions, and other selected economic groups to report advances towards achieving numerous millennial development goals worldwide. These statistical divisions were devised for statistical purposes and is used for carrying out statistical analysis.^[2] The division's first publication was the book World's Women 2000: Trends and Statistics in 2000.

According to the UN, the assignment of countries or areas to specific groupings is for statistical convenience and does not imply any assumption regarding political or other affiliation of countries or territories.^[3]

Subregions by continent

The following is a non-exhaustive list of subregions, arranged alphabetically by region (i.e., by continent); in the UN geoscheme, higher-level, macro-geographical regions are arranged to the extent possible according to continents.
